27   * Tried to deploy v0.4.2 on JBoss 3.2.1 and had a classloading problem again.
28   * The problem seemed to be with JspInfo, line 98. We are using an
29   * ObjectInputStream Class, which then cannot find the classes to deserialize
30   * the input stream.  The solution appears to be to subclass ObjectInputStream
31   * (eg. CustomInputStream), and specify a different class-loading mechanism.
